title: Survival and success rate of one-piece implant inserted in molar sites.
abstract: BACKGROUND
  Recently, the use of one-piece implants (OPI) has become more popular. Since no reports specifically focus on OPIs inserted in molar areas, a retrospective study has been performed.
  
  
  METHODS
  A series of 36 OPIs (Diamond; BIOIMPLANT, Milan, Italy) were inserted into the molar area of patients admitted at the Dental Clinic, University of Chieti, Italy, for oral rehabilitation between January and December 2010.
  
  
  RESULTS
  In our series survival rate (SVR) and success rate (SCR) were 91.7% and 97%, respectively. Statistical analysis demonstrated that no studied variable has an impact on survival (i.e., lost implants) as well as on clinical success (i.e., crestal bone resorption).
  
  
  CONCLUSIONS
  OPIs are reliable devices for oral rehabilitation in the molar areas.
